DuPhos and BPE Ligands: Highly Efficient Privileged Ligands

Catalyst for:
• Stereoselective synthesis of δ-amino acid derivatives via asymmetric hydrogenation of acetylaminopentenoic acid derivatives
• Stereoselective synthesis of manzacidins A and C via stereoselective hydrogenation
• Stereoselective synthesis of tetracyclic core of manzamine A via Rh-catalyzed asymmetric hydrogenation, diastereoselective Diels-Alder reaction, Eschenmoser-Tanabe fragmentation, Chang′s amide formation, and Hofmann rearrangement
• Asymmetric preparation of chiral Cbz-aminodifluorobutyric acid Me ester and its analogs
• Biphasic catalytic hydrogenations in ionic liquids with addition of water as a second solvent
• Preparation of cyclobutane-containing amino acids via asymmetric hydrogenations of cyclobutyl enamides
• Asymmetric preparation of both enantiomers of (dimethoxycoumaryl)alanine as suitable fluorescent peptide labels

DuPhos and BPE Phospholane Ligands and Complexes

In the early 1990s, Burk and coworkers developed new electron-rich C2 symmetric bis(phospholane) ligands. The modular nature of these ligands allowed for variation of both phosphane substituent and b...
